Subject: SGP/ACSM/C1 - Water in inlet sample line
Affected Datastreams: sgpaosacsmC1.a1
Description Data became progressively more noisy causing large spikes in data. These spikes started occurring for longer periods of time during the day before the instrument went down completely on 7/12. The afternoon data (usually 15:00-24:00 UTC) was incorrect because of water condensation in the inlet line and aerosol collection efficiency change. The organic mass loading is around 0 when the condensed water was absorbing all the particles.
Measurements
  • ammonium (Mass concentration of ammonium, ambient aerosol in air.)
  • sulfate (Mass concentration of sulfate, ambient aerosol in air.)
  • nitrate (Mass concentration of nitrate, ambient aerosol in air.)
  • flow_rate (Flow rate, calculated from calibration and inlet pressure)
  • total_organics (Mass concentration of total organics, ambient aerosol in air)
  • emission_current (Emission current)
  • inlet_open (Inlet open)
  • inlet_closed (Inlet closed)
  • vaporizer (Vaporizer)
  • chloride (Mass concentration of chloride, ambient aerosol in air.)

Affected Datastreams: sgpaosacsmC1.b1
Description See below for details of reprocessing that was completed on 20150610. Original DQR category: 4 (Red, Incorrect). ----------------------------------------------------------- The data will be reprocessed with the manufacturer's software to correct errors in the calibration values, collection efficiencies, and instrument response. The data in the current form is incorrect and should not be used.
Measurements
